Chapter 2, Problem 2/082 A commercial airliner with four jet engines, each producing 98 kN of forward thrust, is in a steady, level cruise when engine number 3 suddenly fails. Determine the distance d (measured up or down on the figure) to the resultant of the three remaining engine thrust vectors. Treat this as a two- dimensional problem. The distance d is positive if above the center line of the airplane, negative if below. 98 kN 8.5 m 3 12.5 m 12.5 m 98 kN 2 8.5 m 98 kN 1
